Insects, rodents, microbes, improper post-harvest storage, and other factors are the leading causes of significant food grain loss. An estimated 14 million tonnes of food grain are lost annually in storage in India, primarily as a consequence of insects. Synthetic pesticides and fumigants are the only tools available for controlling these pests, which has led to numerous environmental and effectiveness problems. Phyto-insecticides have long been hailed as desirable alternatives for pest management. Acorus calamus Linn. is a significant Phyto-insecticide that has a wide variety of anti-insect characteristics. Their commercial application is still severely limited due to a lack of formulations. As a result, an emulsion formulation of A. calamus essential oil was attempted. The results clearly demonstrated the formulation's superiority in efficiently managing the pulse beetle. The highest percent oviposition deterrence (96.82), lowest percent egg hatch (44.44), and F1 progeny inhibition rate (99.59) were recorded in the treatment receiving emulsion formulation.
